Title: Lead bushing and lead-acid battery having this lead bushing
Inventor: NAGANO TAKUSHI
IPC: H01M2/30
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To easily perform the highly reliable connection without performing welding work of a polar column and a lead bushing by covering the upper end of the polar column with a wall part and a cylindrical part of the integrally formed lead bushing. SOLUTION: A lead bushing 1 has a cylindrical part 2, a wall part 3 to block up the upper end of the cylindrical part 2 and plural annular swelling parts 4 which are arranged on the lower end side of the cylindrical part 2 and prevent leakage of an electrolyte. This lead bushing 1 is inserted/installed in a cylindrical part 6a arranged in a cover 6 of a lead-acid battery. The upper end of a polar column 7 is inserted into the lead bushing, and the upper end of the polar column 7 and the lead bushing 1 are connected to each other by an electrode agent. In this way, since the lead bushing 1 and the polar column 7 are connected to each other by using the electrode agent, there is no need to weld the polar column 7 and the lead bushing 1 as usual. As a result, welding work can be eliminated, and various problems caused by performing the welding work can be avoided.

Title: Pi controller
Inventor: INOUE AKIRA
IPC: G05B13/02
Filed: 1982-07-29
Abstract: PURPOSE:To improve the precision of a PI controller which varies a proportional gain and an integral time automatically and to facilitate its handling by converting parameters of adaptability into parameters relating to values on a time axis. CONSTITUTION:A PI control constant adjusting part 11 inputs the proportional gain K of a controlled system and calculates the proprotional gain KP and integral time T1 of PI control. Quickness parameters alpha and T are so set that the time when control response reaches 100.alpha(%) as a final value in response to stepwise variation in the command of the controlled system is T. Further, a stability parameter beta is so set that while beta>1.0, beta=1/omegaCTI. Therefore, the parameter beta as an index of stability is settable in addition to the parameters alpha and T as indexes of quickness, so the arithmetic expression of the proportional gain KP and integral time TI is derived from the results of the simulation of many controlled systems.

Abstract: PROBLEM TO BE SOLVED: To obtain the non-reflecting terminal part of an optical fiber having high reliability with good assembly workability by melting the terminal part of the optical fiber removing a coating from it and forming it into a curved surface curing this part. SOLUTION: The coating 2 at the end of the coated optical fiber 1 is removed by a prescribed length to expose the optical fiber (glass part) 3 consisting of a core and clad. The front end 3b of the exposed glass part 3 is arranged between electrodes 4 and 5 of an arc discharge device and is heated and melted by an arc discharge. The end face 3a of the glass part 3 melted by heating is made spherical by surface tension, by which the end face is curved and a non-reflecting terminal part 3a is formed. There is not need for square cutting the end face 3b of the optical fiber 3 prior to heating. The end face held intact after cutting with nippers, etc., is equally well.
